What strikes me about this token is the very high percentage of staking - that's an indication of a use-case. I'm open to being corrected about this, though.
If you’re talking about FUN Savings, those numbers are unverifiable. It is not real staking that can be verified on the blockchain. Around 60% of the supply is supposed to be locked on FreeBitco.in, but around 83% is held on Binance wallets. If you lock your tokens on the site, not only are you trusting FreeBitco.in but also Binance. All these layers of risk, lowering the APY to an insignificant amount, and the token’s historical performance make this a very unattractive offering.
